ALBERT Hf'nevls ANnnAiLPn .TACKslv",A OF LAHABRA, oemnoaivreFirmeninterne* Application i filed November To all whore/t maycoacern:

and RALPH M. JAoKsoNy citizensof theV United States,'residing at LaHabra, county i of Orange, State of California, `have 4invented a newandusetul Fumigation Tape, of Whichthe"followingis a specification: y

It is the object oi this invention to provide a fumigation tape,bywmeanslfof 'which a tree to `be Yumigated maybe lmeasured', and theproper dosage of fumigatingmatef rial for ya tree of that`size'willshowupon the tape, said' dosage beingcorrected in accordancewith thekindof treebeingfumis gated, as well'as in accordance withclimatic conditions, such as the season of the year; and thetemperature. y

The tape also has associated" therewith, means` `for indicating theLproper `length yof time for applying a dosage 1deterniinedby` the tape,Vas well as'meansjorindicating the percent of a normal dose which isbeing applied, at any readingof the tape. 'i

Tapes have been heretofore employed l which 4gave schedules of dosage'for Vvarious heights of trees at the respective'linear markings alongthetape, so thatibylireadlv ing the circumference of a treeup'oir'thetapeya-nd consulting the schedule at that point uponthetape, anormalfdosage for'` a" tree of the height 'of the one 'in question couldbe obtained.

This' normal dosage, however, didnot takev into consideration variationsWhicl'iy should' be made in the1dosa`ge,-in accordance with the kindo'ftree, whetherlemon-orlorangey` and in accordancewithclimaticconditions,1 such `as season 'of the year, and' temperature.'

The invention, in the practical `form Aillus 40 trated, comprises aplurality of tapes,"each` having a plurality of schedulesatthefrespeci-ive linearim'arks, and upon eachsid'e of the tape. "Thedosagesden'oted "by these schedules are arranged for 'the' respectiveheights of trees, and for the respective circumferences denoted by thelinearm'arkiiigfsA of the tape, and *in addition the; schedules upon therespective sides' of a tape at a linear mark, vary in accordance withproper dosage for lemon' and orange trees respectively, and eachplurality of schedules also lvary in accordance with proper dosage fordifferent temperatures, Furthermore, the schedules of the respectivetapes vary to 2, 11921;' i serial No.rsiaaee." Y

In thenpresent `embodiment of vthe invention," four #tapes comprise" aset, and* they are'ipreferably of 4suitable webbingV l and are about 7 5teetlong.` Linear scale markingsVQ` are along-botlrsides of "eachtape;`The-various tapes Lare for usein different seasons of the year, and akey which is@ uporr both sides of a tapeat itsend,has a marking 3denoting the months when the tape is usedi f `The keyincludes'subdivisions "4 for the respective schedules 4employed withVdiiierent temperatures. Ne usually-employ three temperature" "changes,utilizing three schedules, butY as shown in Fig. 3, witlrthisgar`rangement, the tape for the months July-to Oct., preferably is arrangedfor :tour `temperature changesfand four schedules, upon its lemon treeside.

The-key'and schedulesupon one-side ot eachl tape is forrv orangetrees,"as shown in Figs. l andQ, while thekey and schedules upon'the"opposite side -of a tape,` is for lemon trees, as shown in Fig. v. Asacon veiiie'nt indicating means, markings 5 comprising the-'wordOrangesor Lemons arearranged at suitable points along the respective; sides ofa tape.

The temperature ranges for the respective schediileslaremarked intherespective subdivision of a' key,` as shown-at 6; and eachsubdivision also has a vmarking 7, denoting the ma-Xinniinlength of timeVforv applying a dose5as-Well as awmarkingjS denoting the percentage ofa normal dose which is ap plied, when that particular schedule is used.The various sub-divisions of a key also carry an identifying mark 9, sothat when the proper schedule has been determined from the key, it maybe readily identified along the tape, by a similar identifying mark 9a.

A schedule for each sub-division of a key is arranged at the respectivescale markings 2 along the tape. These schedules each comprise theiridentifying mark 9a, a table of linear measurement lO denoting heightsof trees, and a cooperating table indicating dosage, preferably inounces, by marks 1l alongside the indicating marks of table l0.

The dosage denoted by marks l1 is computed to take into considerationfirst of all, the circumference and height of a tree, as in the tape nowin use, and also to take into consideration the additional factors ofkind of tree, whether lemon; or orange, season of the year, andtemperature.

Thus for example, it Will be seen by referring to the drawings, that inJair-Feb., at a temperature of 45-75 degrees, an orange tree Will takean 88% dosage, as shown by sub-division l of the key. lf now a tree is38 ft. in circumference as measured by the tape, and is 34 ft. high,schedule l at the 38 foot mark will show a dosage of 9 ounces.

In July-Octhowever, at the same temperature, an orange tree Will takeonly a 76% dosage; so that the same tree would have a dosage of 7 ouncesas shown by the schedule. A lemon tree, on the other hand, at the sametime of year, namely July-Oct., and at the same temperature, will takean 88% dosage.

It will thus be seen that the improved tape will denote a relativelyhigher dosage for lemon than for orange trees, since the former are ableto take such; an increased dosage, and furthermore that a relativelyhigher dosage is shown for Winter than for summer, since the trees maywith safety be subjected to such an increased dosage in the Winterseason.

As a further example of the Working of the device, it Will be seen thatin Ja1i.-Feb., orange trees take an 88% dosage at a temperature of A5 to75 degrees, but at a tem perature of 76 to 85 degrees, they take only an82% dosage as shown by schedule 2, and at 86 to 98 degrees they takeonly 76% as shown by schedule 3.

ln other Words, the dosage is adjusted for al higher dosage in coldWeather, when the trees will stand the same, than in Warmer weather whensuch a high dosage cannot be safely applied.

The improved tape thus provides linear markings for measuring thecircumference of a tree, and at said markings has schedules denotingdosage for trees of various height, said dosage being adjusted forvariations in the season of the year and for temperature changes, andalso being corrected for either orange or lemon trees.

lVhile we have illustrated and described but one practical embodiment ofthe invention, it will be apparent that various changes may be made inthe details of construction and arrangement Without departing from thespirit of the invention.

What is claimed is:

l. A tape having a graduated scale for measuring one dimension of anobjective, tables at the respective graduations of said scale denotingranges of measurement of another dimension of the objective, and a plurality of dosage tables at the respective graduations of the scale andadjacent said tables of measurement, said dosage tables bearing apredetermined relation to the dimensions of said objective as denoted byboth the graduated scale and by said tables of measurement, and alsobearing a predetermined fractional relationship one to another.

2. A tape having a graduated scale for measuring one dimension of anobjective, tables at the respective graduations of said scale denotingranges of measurement of another dimension of the objective, and aplurality of dosage tables at the respective graduations of the scaleand adjacent said tables of measurement, said dosage tables bearing apredetermined relation to the dimensions of said objective as denoted byboth the graduated scale and by said tables of measurement, and alsobearing a predetermined fractional relationship one to another, andmeans on said tape for identifying the dosage table for use underdifferent existing conditions.

3. A tape having a graduated scale for measuring one dimension of anobjective, tables at the respective graduations of said scale denotingranges of measurement of another dimension of the objective, a pluralityof dosage tables at the respective graduations of the scale and adjacentsaid tables of measurement, said dosage tables bearing a predeterminedrelation to the dimensions of said objective as denoted bv both thegraduated scale and by said tables of measurement and also bearing apredetermined fractional relationship one to another, and means on saidtape for identifying the dosage table for use under different climaticconditions, with objectives of different condition, and with differentkinds of objectives.

In testimony whereof We have signed our names to this specification.
